In most cases, the backlight leakage is not very noticeable and you don’t even get to know about the problem. But, at times, the problem turns out to be severe that it starts affecting the clarity of the image and vision. Hence, it all comes down to the recognition of the problem in the first place, and then going for a fix.

So, without wasting any time, let’s get started:

What are the Causes of Backlight Bleed?


Though it is quite obvious by the name, backlight bleed is the leakage of backlight behind the display. There is a whole big panel of light behind the display that throws lights on the display to create different images.

That said, in case of backlight bleed, what happens is that the display is unable to block all the unnecessary lights that are not required to create the image, which results in leakage of those lights. This not just disturbs your vision but also makes your display look pretty odd.

Although several reasons lead to this problem, the most common ones include manufacturing problems, poor quality control, and faulty design of the monitor. In addition to that, deviation in the alignment of the layers used in IPS panels is also one of the major causes of this issue.

Now in order to counter the problem, it is important to get fully aware of it. So here are some of the types of backlight bleed that are commonly observed in monitors. Let’s check them out:

Types of Backlight Bleed

On a broader level, you will witness the two common types of backlight bleed. These are:

1. Clouding

In this type of Backlight bleed, you will witness some scattered light portions on the screens appearing with some distance between them. The reason behind this is that the light behind the display does not fall on it properly.

Moreover, the scattered light patches indicate that the light falls on some parts and the rest of the part remains dark. This uneven light fall on display causes trouble in vision and image creation.

2. Flash Lighting

This type of backlight bleed is rare and occurs less commonly. In this case, what happens is that the edges of the display throw more light and the center remains darker comparatively.

The light slips out the edges and leaves the center dark. This occurs when the backlight bleed gets severe and needs to be fixed at its earliest.
